Description

Technical Field

[0001] The utility model relates to the field of automobile manufacturing, in particular to a device for processing an automobile left door sill inner plate reinforcement plate. Background Art

[0002] With the development of the automobile industry, people have higher and higher requirements for the quality of automobiles. In the past ten years, my country's automobile production has achieved a substantial growth. With the improvement of people's living standards, automobile manufacturers have been constantly innovating to adapt to the development of the times and the needs of consumers. Automobile manufacturers around the world are also constantly innovating and constantly improving the effectiveness and quality of automobile parts. The inner panel of the automobile threshold is an automobile accessory installed on the automobile threshold for decorating the automobile threshold part, which plays a role in protecting and beautifying the car body. A reinforcement plate will be added inside to absorb impact energy.

[0003] Existing automobile threshold inner panel reinforcements generally adopt a box-type structure to form an independent cube. Since each surface of the automobile threshold inner panel reinforcement is uneven, a cavity structure is formed between the outer portion of the automobile threshold inner panel reinforcement and the automobile threshold inner panel, and a portion of the position contacts the automobile threshold inner panel and is welded to the threshold inner panel at the contact position (protrusion). Therefore, the outer portion of the automobile threshold inner panel reinforcement plate is adjacent to the side of the automobile threshold inner panel but leaves a certain space as an energy absorbing cavity. The box-type structure of the automobile threshold inner panel reinforcement becomes another energy absorbing cavity. It plays an energy-absorbing role in a collision. Some positions between the automobile threshold inner panel reinforcement and the threshold inner panel need to be installed with bolt fasteners. Therefore, holes should be drilled at the corner plate positions of the reinforcement plate to provide channels for bolt fastening. In order to ensure the accurate installation position of the reinforcement plate and the automobile threshold inner panel and fully obtain good force transmission and energy absorption effects, the position of the holes on the reinforcement plate must be accurate. Therefore, when drilling holes, the operator needs to press the reinforcement plate tightly with his hands to limit its movement during the drilling process. However, this fixing method is more laborious, and the vibration during drilling can easily cause hand fatigue.

[0004] Therefore, in view of the above-mentioned method of punching holes by squeezing and fixing the reinforcing plate with the operator's hands, which is rather laborious and easily causes hand fatigue, a positioning tool adapted to the shape of the reinforcing plate is required to cooperate with the hole opener. Utility Model Content

[0005] In order to overcome the problem that the method of hole opening by squeezing and fixing the reinforcing plate by the operator's hands is laborious and prone to hand fatigue.

[0006] The technical solution of the utility model is: a device for processing a reinforcement plate of an inner panel of a left door sill of an automobile, comprising a hole punching platform, a tail positioning mechanism, an adjusting bracket assembly and a corner plate positioning frame; the hole punching platform is placed on the processing platform and is installed and anchored with the processing platform through bolts at four corners, a tail positioning mechanism is installed on the rear side of the upper end of the hole punching platform, the tail plate of the reinforcement plate is plugged and fixed in the tail positioning mechanism, and the adjusting bracket assembly that can slide horizontally is symmetrically arranged on the left and right sides of the tail positioning mechanism, and a U-shaped corner plate positioning frame adapted to the corner plate structure of the reinforcement plate is installed at the front end of the adjusting bracket assembly, and the two corner plate positioning frames are oppositely engaged with the corresponding corner plate side of the reinforcement plate.

[0007] Preferably, after the user aligns the tail plate structure of the reinforcement plate with the tail positioning mechanism and inserts it longitudinally to fix it, the user moves the adjustment bracket assembly oppositely to make the angle plate positioning frame rest against the edge of the angle plate of the reinforcement plate to lock it. The tail positioning mechanism and angle plate positioning frame designed for the tail plate and angle plate structure of the reinforcement plate can synchronously lock the head and tail ends of the reinforcement plate from the horizontal plane. After locking, use the hole opening tool to align with the marked points on the angle plate to perform hole opening processing.

After one end of the adjustment bracket assembly is longitudinally inserted into the slot to the bottom of the slot, it is then laterally slid into the slide groove. The adjustment bracket assembly can move along the slide groove to get close to or away from the corner plate of the reinforcement plate.

[0010] Preferably, the adjustment bracket assembly includes a slider and a through tube; the slider is longitudinally inserted into the slot and slides laterally along the slide groove, the front end of the slider is fixedly connected to the through tube, and a through hole is opened on the outer wall of the through tube. The slider is a T-shaped structure adapted to the slot and the slide groove, and will not fall out from the front end of the mounting seat after being inserted into the slot and the slide groove. While the through tube serves as a support member of the connecting frame, the connecting frame can also slide in the through tube.

[0011] Preferably, the adjustment bracket assembly also includes a connecting frame and adjustment holes; one end of the connecting frame is inserted into the through pipe, and the other end is fixedly connected to the angle plate positioning frame. 5-12 adjustment holes are evenly spaced on the end of the connecting frame in the through pipe.

Fastening bolts are inserted into the through holes, adjustment holes and pin holes in the same vertical axial direction to fix the through pipe and the connecting frame, and the through pipe and the hole-opening platform at the same time. After the connecting frame extends out of the through pipe to a suitable length, the fastening bolts are inserted into the corresponding through holes, adjustment holes and pin holes to lock the through pipe and the connecting frame on the hole-opening platform at the same time. When the through pipe is locked, the slider will not move again in the slide groove.

[0013] Preferably, a U-shaped bracket is fixedly connected between the front ends of the two connecting frames, and the angle between the bracket and the horizontal plane is 15-30 degrees. The oblique straight part of the bracket is made of transparent hard resin material and has LED lamp beads inside. Wind holes are opened on the horizontal part of the bracket, and the horizontal part is connected to the air outlet of the external fan through a hose. While the hole is being opened, the external fan conveys air flow into the bracket, which is blown obliquely downward from the wind hole to the corner plate of the reinforcing plate to blow away the waste chips generated by the opening.
